Liquen estriado del adulto: experiencia en un servicio de Dermatología / Adult lichen striatus: experience in dermatology service

Introducción. El liquen estriado es una dermatosis que sigue el trayecto de las líneas de Blaschko, se presenta característicamente en población pediátrica y es rara en pacientes adultos. Objetivo. Describir las características epidemiológicas y clínicas de los pacientes adultos con diagnóstico de liquen estriado diagnosticados en el período 1998-2010 en el Hospital Nacional Daniel Alcides Carrión (HNDAC). Material y Métodos. Estudio descriptivo de tipo serie de casos. Se revisó las historias clínicas de los casos de liquen estriado y se obtuvo datos epidemiológicos (edad, sexo), antecedentes de importancia (comorbilidad) y aspectos clínicos de los pacientes (tiempo de enfermedad, características de las lesiones, síntomas asociados). Los datos obtenidos fueron registrados en un instrumento de recolección de datos. Resultados. Ingresaron al estudio un total de 10 casos, el promedio de edad fue de 27 años (rango 16-48 años), 80% de los casos fueron de sexo femenino. Las lesiones clínicas eran placas formadas por pápulas milimétricas levemente descamativas de color piel, eritematosas o ligeramente hipopigmentada de distribución lineal y que seguían las líneas de Blaschko. Las lesiones se presentaron con mayor frecuencia en miembros inferiores (60%) y tronco (40%). El síntoma más frecuentemente referido porlos pacientes fue prurito (70%). La comorbilidad más frecuente fue atopía que se presentó en 40% de los pacientes. Conclusión. Los pacientes adultos con diagnóstico de liquen estriado del HNDAC presentan características clínicas similares a las descritas en pacientes pediátricos. La atopía constituye la comorbilidad más frecuente.

Back ground. Lichen adult is a dermatosis that follows the Blaschko lines, tipically it present in pediatrics population and is rare in adult patients. Objective. Describe the epidemiological and clinical characteristics with diagnosis of lichen striatus that were diagnosed between1998-2010 at National Hospital Daniel Alcides Carrion (HNDAC). Material and methods. Descriptive study of a case series. Clinical records were reviewed, obtaining epidemiological data (age, genre), background of importance (comorbidity) and clinical aspects of the patients ( time of illness , characteristics of the injuries, associated symptoms) that were recorded in a data collection instrument. Results. Ten cases were enrolled, the age average was 27 years old (range 16-48 years), 80% of cases corresponded to females. Clinical injuries were plates formed by millimeter papules slightly descamatives of skin color, eritematoses or slightly hypopigmentated od linear distribution and that followed the blaschko lines. Injuries were presented with more frequency at the lower limbs (60%) andin trunk (40%). The most frequent symptom was the pruritus (70%).The most frequent comorbidity was the atopy, presents in 40% of the patients. Conclusion. Adult patients with diagnosis of lichen striatus atthe HNDAC present clinical characteristics similar to pediatrics patients. The comorbility more frequent is the atopy.

Oral involvement of chronic graft-versus-host disease in hematopoietic stem cell transplant recipients.

Oral manifestations are common in patients who are diagnosed with chronic graft-versus-host-disease (cGVHD). These manifestations can present as oral mucosal lesions, salivary gland dysfunction, or reduction of the mouth opening due to cutaneous sclerosis. Although several studies have reported the prevalence of oral involvement in cGVHD, few have reported details of different types and severity of oral lesions of cGVHD, according to the NIH. Furthermore, the authors are aware of only one published study concerning oral manifestations of cGVHD in Brazil. The purpose of this study was to evaluate the prevalence and severity of oral involvement of cGVHD. Oral evaluation of hematopoietic stem cell transplant (HSCT) recipients was conducted on 22 patients (12 men and 10 women) from December 2007 to May 2009. The following categories were assessed: Age, gender, underlying disease, time postHSCT, history of GVHD, therapy for GVHD, oral lesions, xerostomia, resting salivary flow rate, and mouth opening. Oral lesions were classified according to NIH criteria, and the results were submitted to a descriptive analysis. According to the NIH, patients presented diagnostic (40.9%), distinctive (31.9%), and common (9.1%) features of oral cGVHD. Oral involvement of cGVHD was identified in 81.8% of patients, 68.2% as mucosal lesions and 59.1% as salivary gland dysfunction. Reduced mouth opening was observed in 12 patients (80%), with one case associated with cutaneous sclerosis. Oral involvement was frequent in these patients; for many, it was the first clinical manifestation of cGVHD.

Lichen striatus: description of 89 cases in children.

Lichen striatus (LS) is a benign, self-limited, linear, inflammatory dermatosis of unknown etiology that usually affects children. We analyzed 89 cases in regard to age of appearance, sex, race, symptoms, seasonal incidence, localization of lesions and affected side of the body, and presence of atopy. Lesions predominated on the inferior limbs, with no preponderance of any age, and were asymptomatic in the majority of the instances. There was no difference in the incidence of LS in regard to the season of the year. A possible association of lichen sclerosus with atopy and pruritus was observed.
